For years, David Bellamy was one of the best known faces on TV. A respected botanist and the author of 35 books, he had presented around 400 programmes over the years and was appreciated by audiences for his boundless enthusiasm. Yet for more than 10 years he has been out of the limelight, shunned by bosses at the BBC where he made his name, as well as fellow scientists and environmentalists. His crime? Bellamy says he doesn’t believe in man-made global warming. Here he reveals why - and the price he has paid for not toeing the orthodox line on climate change. “When I first stuck my head above the parapet to say I didn’t believe what we were being told about global warming I had no idea what the consequences would be. I am a scientist and I have to follow the directions of science but when I see that the truth is being covered up I have to voice my opinions. According to official data, in every year since 1998 world temperatures have been getting colder, and in 2002 Arctic ice actually increased. Why, then, do we not hear about that? The sad fact is that since I said I didn’t believe human beings caused global warming I’ve not been allowed to make a TV programme.

At the beginning of this year there was a BBC show with four experts saying: “This is going to be the end of all the ice in the Arctic,” and hypothesising that it was going to be the hottest summer ever. Was it hell! It was very cold and very wet and now we�ve seen evidence that the glaciers in Alaska have started growing rapidly - and they’ve not grown for a long time.

I’ve seen evidence, which I believe, that says there has not been a rise in global temperature since 1998, despite the increase in carbon dioxide being pumped into the atmosphere. This makes me think the global warmers are telling lies - carbon dioxide is not the driver.

The idiot fringe have accused me of being like a Holocaust denier, which is ludicrous. Climate change is all about cycles, it’s a natural thing and has always happened. When the Romans lived in Britain they were growing very good red grapes and making wine on the borders of Scotland. It was evidently a lot warmer. If you were sitting next to me 10,000 years ago we�d be under ice. So thank God for global warming for ending that ice age; we wouldn’t be here otherwise. People such as former American Vice-President Al Gore say that millions of us will die because of global warming - which I think is a pretty stupid thing to say if you’ve got no proof. And my opinion is that there is absolutely no proof that carbon dioxide is anything to do with any impending catastrophe. The science has, quite simply, gone awry. In fact, it’s not even science any more, it’s anti-science.

The thing that annoys me most is that there are genuine environmental problems that desperately require attention. I’m still an environmentalist, I’m still a Green and I’m still campaigning to stop the destruction of the biodiversity of the world. But money will be wasted on trying to solve this global warming “problem” that I would much rather was used for looking after the people of the world.
